This is a copy of my go to tool. If they got 1/10th of the performance in the copy, it would be worth owning at that price. The two things that will kill it quickly are the mandrels not being tough enough and the handles collapsing. I've set 1000's of nutserts with my NCG but if this one will set a couple hundred without dying, it would be better than the short handle one and cheaper than the Marson.
I also have the Marson. It is okay, prefer the NCG.
Key is not tipping the tool over sideways when you are setting a nutsert. That breaks the mandrels.
